我正在使用Pentaho 7.1,我的目标是写到Hadoop数据库。我正在使用Pentaho的“ Hadoop文件输出”组件来尝试写入Hadoop。我无法正确创建hadoop集群,配置所有参数后出现以下错误:
[2018/10/30 23:10:53 - [Named][1] cluster: tst - Root Directory Access: FATAL We couldn't run test Root Directory Access. 2018/10/30 23:10:53 - Named cluster: tst - null 2018/10/30 23:10:53 - Named cluster: tst - java.lang.NullPointerException 2018/10/30 23:10:53 - Named cluster: tst - at org.pentaho.bigdata.api.hdfs.impl.HadoopFileSystemLocatorImpl.getHadoopFilesystem(HadoopFileSystemLocatorImpl.java:62) 2018/10/30 23:10:53 - Named cluster: tst - at org.pentaho.bigdata.api.hdfs.impl.HadoopFileSystemLocatorImpl.getHadoopFilesystem(HadoopFileSystemLocatorImpl.java:49)]
hadoop环境已被kerberized。有没有人使用Pentaho 7.1版写过有关kerberized hadoop的文章?
非常感谢您的支持
